Estudio de dos especies de dinoflagelados marinos productores de Floraciones Algales Nocivas (FANs) : "Alexandrium ostenfeldii" y "Protoceratium reticulatum"

Abstract

Esta tesis tiene como objetivo profundizar en el conocimiento de las estrategias de vida de dos especies de dinoflagelados productores de floraciones algales nocivas (HAB): Alexandrium ostenfeldii y Protoceratium reticulatum. Debido a que durante las últimas cuatro décadas a nivel mundial eventos de floraciones algales nocivas producidos por dinoflagaledos han incrementado su frecuencia, cobertura geográfica, e intensidad, es de gran importancia estudiar el ciclo de vida de las especies involucradas para conocer su estrategias de vida y entender su interacción con el medio ambiente. Esto último es de gran importancia debido a que actualmente no se conocen métodos efectivos para contrarestar las floraciones de dinoflagelados. Dentro de los dinoflagelados productores de FAN, los géneros Alexandrium y Protoceratium destacan por su nocividad debido a la producción de toxinas y al deterioro del medio marino en zonas productivas. Por lo tanto, estudiando las características básicas de estas especies podremos entender y evaluar acciones para reducir los riesgos y los impactos negativos sobre la salud humana y las actividades productivas. En este trabajo de tesis se llevaron a cabo diferentes objetivos específicos para abordar el objetivo general. Uno de ellos fue el estudio de las condiciones óptimas de crecimiento, producción y germinación de quistes y producción de toxinas en Alexandrium ostenfeldii bajo diferentes condiciones de salinidad y temperatura. En el segundo objetivo se realizó una caracterización genética, morfológica y relación filogenética de las cepas de Protoceratium reticulatum. Se realizó una diferenciación filogenética, morfológica y toxinológica. El tercer objetivo estudió el ciclo de vida de Protoceratium reticulatum, en el se determinó los patrones de división asexual y la fase sexual de la especie; se realizó una caracterización de diferentes fases del ciclo de vida; y se estudiaron los procesos de enquistamiento y germinación. En el cuarto objetivo se estudiaron las condiciones óptimas de crecimiento y producción de quistes bajo diferentes condiciones de salinidad y temperatura mediante un análisis de diseño factorial.

This thesis aims to deepen the knowledge of life strategies of two dinoflagellates producing of harmful algal bloom (HABs): Alexandrium ostenfeldii and Protoeratium reticulatum . Because during the past four decades worldwide events of harmful algal blooms caused by dinoflagaledos have increased their frequency, geographical coverage and intensity, it is of great importance to study the life cycle of the species to know their livelihood and well understand their interaction with the environment. This is of great importance because currently still no known effective methods to counter dinoflagellate blooms. Within the dinoflagellate Alexandrium gender and Protoceratium known for their toxicity and harmfulness due to the production of toxins and deterioration of the marine environment. Therefore, studying the basic features of these species we can understand and evaluate actions to reduce risks and negative impacts on human health and productive activities. In this thesis were carried out different specific objectives to address the overall objective. One of them was the study of optimal growing conditions, production and germination of cysts and toxin production in Alexandrium ostenfeldii under different conditions of salinity and temperature. The second objective was genetic characterization, morphological and phylogenetic relatedness of strains reticulatum Protoceratium be performed. a phylogenetic, morphological differentiation and will toxinológica. The third objective of the study was the life cycle of Protoceratium reticulatum. The patterns of sexual asexual and sexual division of the species were determined; A characterization of the different phases of the life cycle was carried out; And the entrenchment and germination processes were studied. In the fourth objective, optimal growth conditions and the production of cysts under different salinity and temperature conditions were studied by factorial design analysis. In the fourth objective, the optimal conditions of growth and production of Protoceratium reticulatum cysts under different salinity and temperature conditions were studied by factorial design analysis.

Esta tese ten como obxectivo afondar no coñecemento das estratexias de vida de dúas especies de dinoflaxelados productores de floración algas nocivas (HAB): Alexandrium ostenfeldii y Protoceratium reticulatum. Debido a que durante as últimas catro décadas eventos mundiais de proliferación de algas nocivas causadas por dinoflagaledos aumentaron a súa frecuencia, cobertura xeográfica e intensidade, é de gran importancia para estudar o ciclo de vida das especies a coñecer a súa subsistencia e ben comprender a súa interacción co medio ambiente. Isto é de gran importancia, pois métodos eficaces actualmente aínda non coñecidos para combater blooms de dinoflaxelados. Dentro do xéneros de dinoflaxelados Alexandrium e Protoceratium coñecidos pola súa toxicidade e nocividade debido á produción de toxinas e de deterioro do medio ambiente mariño. Polo tanto, estudar as características básicas destas especies, podemos comprender e avaliar accións para reducir riscos e impactos negativos sobre a saúde humana e actividades produtivas. Nesta tese realizarase diferentes obxectivos específicos para acadar o obxectivo xeral. Un deles é o estudo de condicións de crecemento óptimo, a produción ea xerminación de cistos ea produción de toxinas en Alexandrium ostenfeldii baixo diferentes condicións de temperatura e salinidade. A segunda caracterización xenética obxectivo, parentesco morfolóxica e filoxenética de cepas reticulatum Protoceratium realizarse. un filogenética, diferenciación morfológica e toxinológica. O terceiro estudo obxectivo do ciclo de vida de Protoceratium reticulatum nos patróns son determinados división fase asexuada e sexual da especie; unha caracterización das diferentes fases do ciclo de vida será executada; e serán estudados procesos pétreas e xerminación. No cuarto obxectivo, foron estudadas as condicións óptimas para o crecemento e produción de cistos baixo diferente salinidade e temperatura por medio da análise deseño factorial.
